Perełkiewicz approached the TV test picture in purely artistic terms, as a scheme which he combines or decorates with various ideograms. Soon, the test pattern evolved towards different color varieties and changed into a net of lines, where the artist inserts shapes and then multiplies them. The next model was the structure of a stained glass, where lead framework with its distinct outline holds the lambent panes of color. The artist uses them especially when they combine into whole structures or merge with architecture, e.g. in the arched gothic windows or rosettes.
